ABSTRACT:
The present invention discloses a method for preventing erroneous take-over in a redundant server system, and the method is used for a server system having a primary server for continuously producing heartbeat packets and sending the heartbeat packets to a redundant server of the server system. If the redundant server has not received any heartbeat packet, a redundant external transmission unit of the redundant server will send a detecting signal to the primary server. If the redundant external transmission unit has not received an acknowledged signal from the primary server, the redundant server will take over the primary server to continue providing network services.
